There, she lost control of her RIB and it capsized, resulting in eight people entering the water, some beneath the inverted boat. All managed to get clear of the upturned hull and were quickly rescued by another RIB. One passenger was injured and subsequently air-lifted to hospital for medical treatment. A school party staying at the Plas Menai National Watersports Centre had set out on an authorised powerboat journey within the Menai Strait to go kite flying. Three RIBs carried the group, each driven by a qualified professional instructor. However, the assistant instructor (AI) helming RIB 6, the RIB that capsized, was much less experienced than the other two. When the party arrived at their destination, the weather was unfavourable for kite flying and the two experienced instructors agreed an ad-hoc alternative plan. This involved leaving the Menai Strait to give their passengers a more interesting and exciting trip in the outer channel. They did not adequately brief the AI, or fully consider her inexperience. They did not seek permission from the course supervisor to deviate from the approved plan, as required by Plas Menai procedures, and their revised plan involved an element of “thrill riding” which was not an approved activity at the centre. Initially all was well, but the AI was allowed to stray from the others and take RIB 6 into particularly rough waters. Realising that she was heading in to danger, the AI turned the RIB, but lost control and it capsized. Fortunately all on board escaped without serious injury, and were quickly rescued by RIB 5. The two experienced instructors decided to recover RIB 6, and so landed most of the students, including those rescued from the water, ashore on a nearby beach. The centre was not informed of the accident, but the coastguard was contacted by mobile telephone with a request for the local RNLI lifeboat to assist recovering the upturned RIB. Meanwhile, on the beach, one student’s condition deteriorated and he required helicopter evacuation to hospital. The other students were unhurt, and were later returned to the centre. The investigation identified a number of safety issues including the planning, control, and leadership of the activity, and communications shortcomings.

AD 400–1100 in Wales are still comparatively rare discoveries, although the number is gradually increasing. Apart from elite sites, notably hillforts in the earlier part of the period, they are often only recognized as a result of radiocarbon dating as diagnostic artefacts are usually rare.

  • Anglesey Plants and the Flora Group in 2014: Ian Bonner
    Anglesey Plants and the Flora Group in 2014: Ian Bonner (As appeared in the Welsh Bulletin of the BSBI No.95 February 2015) Before the first indoor meeting at Treborth in March Pat Denne used the 9597 records added in 2013 to update the map showing the total taxa recorded in each of the 800 monads. Andrew Dixon made an electronic version of it available for subsequent reference. At the meeting it was again agreed to concentrate effort on collecting monad data toward the Atlas 2020, a future county flora and keeping the Rare Plant Register up to date. Barry Wrightson kindly agreed to take over the circulation of information about recording days and the coordination of bookings. Over the weekend of 26-27th April Professor John Richards and Dr Tim Rich led a Taraxacum workshop at Treborth, which included field visits to parts of Anglesey and Caernarfonshire. Some 39 taxa were noted on Anglesey, of which 26 were new VC records and will be published in Plant Records in due course. This illustrates the need for targeted recording of difficult taxa to back up basic monad coverage in the run-up to Atlas 2020. Atriplex species (Oraches) on coastal strandlines come into this category. They featured in the 2013 Report and Paul Green came up in early September to assist and make collections. Based on further work this year, it appears that as well as six species, the Anglesey coast may have a complex of four different hybrids. Material is now with the BSBI Referee for the genus. Atriplex portulacoides (Sea-purslane) is one that is easy to spot.

  • Sub Aqua Diving in & Around Snowdonia
    Sub Aqua Diving in & around Snowdonia Introduction Sub-aqua or scuba equipment allows divers to explore the wonderful underwater environment all over the world. The sport has been established in North Wales for many years, with retail outlets, air-supplies, dive-boats and support facilities increasing year upon year. The letters S.C.U.B.A. stand for Self Contained Underwater Breathing Apparatus. Snowdonia, the Lleyn Peninsula and Anglesey have a wide variety of marine dive-sites. Reefs, rocks, shipwrecks and even submerged caverns make North Wales an extremely popular destination for both novice and experienced divers alike. Even when the weather is bad, a commercial dive-site at Llanberis in the heart of the Snowdonia National Park ensures that there is always somewhere to dive. Apart from the sheer enjoyment of being underwater, there are many other aspects to the sport of scuba-diving. Some enjoy the thrill of exploring the many shipwrecks that have occurred around the Welsh coast, perhaps taking things a little further to enter the world of marine archaeology and research into the history of these maritime tragedies. Others love to observe and identify the incredible marine-life that flourishes in these waters, possibly progressing to become involved in underwater photography, marine conservation and species recording. For anyone already qualified to dive, check the Nautical Archaeology Society website at www.nasportsmouth.org.uk and the Seasearch website at www.seasearch.org.uk History The sport of scuba-diving began shortly after the Second World War, when enthusiasts adapted any available equipment to allow them to explore the underwater world.
